MINE can.

Application filed October 21, 1924. Serial No.l 744,915.

This invention relates to certain new and useful improvements in mine cars and more particularly to steel mine cars, the object being to provide a construction of mine cail in which the sides are formed of a series of sections so that th-ey can be rebuilt at the mine, thereby overcomingnow existing in steel mine cars where the sides are formed of a plate bentto the proper form. y

Another object of my invention is to provide a mine carin which the angles of the sides are formed of rolled sections so as to provide a heavier cross section in the angle parts whereby a stronger and more durable mine oar will be formed than when the sides are formed of a single pl n In mine cars now in use .the cars are often wrecked, the sides being bent and deformed to such an extent that it is impossible to rebuild the cars at the coal mine and in fact, impractical to rebuild them aty all and the object of my invention is to provide a mine car in which the sides are formed of sections so that in case a car is wrecked, the car can be rebuilt at the mine by th-e average blacksmith. l

The preferred form of steel mine car now in use is either provided with an oblique offset or a vertical ol'lset and these offsets are obtained by bendingl a single plate tothe proper angle so as to form a complete side,y while with my improved construction, l form the offset of a series of angles rivet-ed or bolted together so that they can be talzen apart and straightened so to rebuild the mine car readily without any great expense.

Gther and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

ln the drawings7 Figure 1 shows a side elevation of a min-e car constructed in accordance with my invention; y

Figure 2 a bottom plan view;

Figure 8 is a front end elevation, partly broken away;

Figure Ll is a rear end elevation;

vFigure 5 is a modified form showingr a detail vertical section showing,- the manner of constructing the vertical offset of angle irons;

Figure 6 is a vertical section of a slightly modified form showing an oblique offset; and

the difficulties Figure 7l is a vertical section formed vof three angle irons used in connection with steel bottom. f

.ln carrying figures 1 to l,

plates 1, angle t7ether and preferably througli'to the ribs i binders ll, said rib or binders extending rom the upper edge of the vertical side ele-.tes 1 under the bottom of the carto the ipper edge of the opposite vertical side plate, the side plates beingvreinforced by The angle iron out my invention as shown in I construct the sides of vertiangle irons o; 4e is bolted to the wooden bottom 6 by bolts 7, which extend through the rib or vbinders l 4as clearly shown; i

Ther bottom of the car in the preferred embodiment of the invention is formed of wood as clearly shown `and is reinforced by cross sills .8 at its ends, andaxle bases 9 are bolted to the bottom as clearly shown in which are mounted axles provided'with the usual wheels, the particular construction of axle forming' no part of my invention.

Extending longitudinally through the center of the car is a draft bar 10, the car being' provided with bumpers 10 at its ends as clearly shown. 'lhefront end of thecar is closed by an end door 11 and the rear by an end door 12 and the front rib 13 is braced shown at 11i and the other ribs are offset shownat 15 to provide a rigid support for the angles.

ln the form shown in Figure 5 the sido plates 16 have connected to their lower edges Z bars 17, which are bolted to angles 18, Said bolts extending through the ribs 19 and wooden bottom 20.

ln the fo m shown in Figure 6 mine car is provided with an oblique offset, the` 2 bar 17" being` employed to provide an upwardly slopingfportion instead of a horizontal portion so that a rigid connection to the side platos 16 and an l i irons-18 can be formed,A the binderor rib l9 being)- constructed substantially the same aC4 shown in the other embodiments of my invention and the upper edges of all of the side plates are reinforced by angle irons as clearly shown.

1n the modificationshown in Figure 7 a construction is shown substantially the same as shown in Figures 1 to l with the enception that a steel bottom 2O is used and comprises side plates 1, angles 2', 3 and d".

In building up the sides of the car these angle irons are assembled and either bolted irons 2 V3 and l bolted n or riveted to the ribs or binders and when a car becomes damaged in use, the bolts can either' be removed or the ri vets cnt so that the angles constituting the sides olE the car can beY removeifl and straightened and re` placed.

While I have shown certain details et construction of a mine ear, it is, ot course, imderstood that I do not Wish to limit myseit' to these Vdetails as my invention coin sists in constructing a steel mine car in which the angles of the sides are termed ot rolled sections so as to increase the strength and to provide a mine car with sides termed ot a plurality oit sections which can be easily assembled to build a car and which can be easily removed to repair the same.

From the foregoing description it will be seen that I have provided a metal mine car with. offset sides so constructed that the car body can be formed with a Wooden bottom or a metal bottom, the offset sides being formed of upper vertically disposed plates and a series of angles 'formed ot rolled setions connected together and to the ribs of the car to allow the sections to be readily detached in order to repair the body et the car When it becomes damaged in use.

It Will also be seen that I have provided a car body With open ends closed by end gates and constructed with ribs or binders to which the plates and angles are connected by rivets or bolts so that the sections can be readily assembled or detached when it becomes necessary to repair the car. In the description I have not described the details of construct-ion of the entire body et the car as my invention consists in the forming oit' the sides of the body of sections which can be reshaped in order'to allow the body ot the car to be rebuilt at the mine, thereby overcoming the ditlieulties new existing in forming the sides of the car et' a single plate bent to form offset sides.

What I claim is:

l. A body for mine cars comprising vertically disposed side plates, and a series ot overlapping angle plates connecting said side. plates to the bottom ot the car to forni a car body with otlset sides.

2. A mine car comprising a bottom, a rolled angledsection, orI plate, connected to said bottom, a second rolledv angled section or plate, connected. to the lirst mentioned angled sestion or plate, a third rolled angledl section or plate connected to the second mentioned rolled. angled section or plate, upper part ol sides connected to the last mentioned rolled angled section or platoI and ribs e i-l tending aronniil said plate and under thei bottom oit said car and to Wh ich said rolledIv angled section or plates are connected. y

3. A mine car comprising a body having oilset sides, the offset sides being formed ot upper verti'ally disposed metal plates and a series el rolled angled sections or plates connecting said vertically disposed lplates to the bottom ot the car, ribs extending around said rolled angled sections or plates and means tor connecting said plates to said ribs.

la A. metal mino fiar having ol'llset sides, each side being formed ot a series of rolled. angled sections connected together and vertically disposed side plates connected to the upper angled section, said side plates having angles secured to the upper edges thereof.

5. A mine car having its sides termed ot metal plates composed et vertically disposed upper plates and rolled angled sections or plates, connectingsaid vertically disposed plates to the bottoni of the car, said plates being detachably connected to ribs extend! ing around the outside of the car.

6. A mine car comprising a bottom, a rolled angl-ed section connected to said bottom, having one of its legs ext-ending vertically upwardly therefrom, a rolled angled sect-ion or plate connected to the vertical portion ol the lirst mentioned angled section having its horiiiontal leg extending outwardly there-- trom, a rolled angled section or plate connected to the last mentioned section or plate having a vertical leg and a side plate connected to the vertical leg ot the last mentioned angled section or plate, said plates being detachably connected to ribs' extendingraround outside ot thebody ot the car.

7. A metal mine ear having offset sides formed of a series of rolled angled sections or plates and vertically disposed plates, ribs extending around the outside otsaid plates, and under the bottom ot the car and bolts or rivets connecting said rolled angled sectionsand plates to said ribs.
